Replace printk_ratelimited with dev_err_ratelimited which
adds dev_printk meta data. This is used by journald to
add disk ID information to the journal entry.
This re-worked change is from a different patch series
and utilizes the following suggestions.
- Reduce indentation level (Andy Shevchenko)
- Remove unneeded () for conditional operator (Sergei Shtylyov)
